Is Your INFINITI I35 Washer Pump Failing?
A working washer system is critical for safe driving, especially in bad weather or dusty conditions. When the pump fails, you lose the ability to clean your windshield on the fly. For the 2002-2004 INFINITI I35, the washer pump is a common wear item that is straightforward to diagnose and replace.
Common Symptoms of a Bad Washer Pump
- No Sound, No Fluid: You press the washer button and hear nothing. This often points to a dead pump or an electrical issue like a blown fuse.
- Pump Hums, But No Fluid Sprays: If you can hear the pump motor running but no fluid comes out, the pump's internal impeller may have failed, or there could be a clog in the lines or nozzles.
- Weak or Uneven Spray: A dying pump may lose pressure, resulting in a weak stream that doesn't effectively cover the windshield.
- Leaking Fluid: You might notice a puddle of blue or purple washer fluid under the front passenger side of the car. The pump body can crack over time, causing leaks from the reservoir.
Choosing a New Aftermarket Pump
For a vehicle like the 2002-2004 I35, a new aftermarket windshield washer pump is often the most practical and cost-effective choice. The original equipment (OEM) pump from INFINITI can be expensive, and for a simple component like this, the quality and reliability of a reputable aftermarket brand are more than sufficient.
Trico is a well-known brand in the wiper and washer system industry. Their pumps are designed to be easy-to-install, direct-fit replacements that meet or exceed original performance. Given the straightforward nature of this part, a Trico pump offers a reliable repair without the high cost of an OEM part.
Pro Tip: Check the Grommet!
The washer pump seals to the reservoir with a small rubber grommet. It's common for this grommet to get old and brittle, causing leaks. Many new aftermarket pumps come with a new grommet. Even if your old one looks okay, it's always best to replace it when you install a new pump to ensure a leak-free seal.
Installation Overview
Replacing the washer pump on an I35 is a job most DIYers can handle. The washer fluid reservoir and pump are typically located in the front passenger-side wheel well. Access involves jacking up the vehicle, removing the front passenger wheel, and pulling back the plastic fender liner. From there, the pump is usually held in by a friction fit into the reservoir. You simply disconnect the electrical connector and fluid hose, pull the old pump out, and press the new one in.

Frequently Asked Questions
Where is the windshield washer pump located on my 2002-2004 I35?
The pump is located at the bottom of the windshield washer fluid reservoir. You can access it by removing the front passenger side wheel and pulling back the inner fender liner.
Can I replace the washer pump myself?
Yes, this is a very DIY-friendly job. It requires basic hand tools, a jack, and jack stands. The process typically takes less than an hour.
My pump makes noise but nothing sprays out. Is the pump bad?
Not necessarily. First, check for clogged washer nozzles on the hood—you can often clear them with a small pin. If the nozzles are clear, the pump's internal parts may have failed, or the fluid lines could be clogged or disconnected. If you hear the motor, the electrical part is working, but the pump itself is likely the problem.
Is there a fuse for the windshield washer pump?
Yes. Before replacing the pump, it's a good idea to check the fuse. A blown fuse is a simple fix. The fuse location for your I35 should be detailed in your owner's manual or on the fuse box cover itself.

No, there are no specific recalls or technical service bulletins (TSBs) from INFINITI or the NHTSA for the windshield washer pump on the 2002-2004 I35. There are, however, unrelated recalls for airbag inflators for this vehicle range.
